Created attachment 118733 [details] Invalidation problem When applying the 'Droid Arabic Naskh' font to the 'elements' word, a too small invalidation occurs that leaves out an invalid part of the document, then the whole document is invalidated. The result and the invalidation command can be seen in the screenshot. The height of the invalidation is just 789 twips, that is 1/4 of a tile, so just a single tile gets invalidated vertically.
Fixed now with: http://cgit.freedesktop.org/libreoffice/core/commit/?id=12e3b51abe883202af09769873f87b27d7de118b
